0 all whom it may concern:

Be it known that l, LAURA ALLIon SALT- HOUSE, a citizen of the UnitedStates of Americal-esiding at Cuyahoga Falls, in the county of Summitand State of Ohio, have invented certain new and useful Improvements inSafety Lamp-Chimneys and Holders, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a safety lamp chimney and holder and has forits principal object the production of a simple and efficient means forpositively holding the chimney upon the burner and preventing the samefrom being accidentally displaced therefrom.

Another object of this invention is the production of a safety lampchimney and holder wherein the arms of the holder are constructed so asto bear upon the side portions of the chimney under normal conditionsfor holding the chimney against accidental displacement, these armsbeing capable of being swung outwardly at their upper ends so as todisengage the chimney and permit the same to be removed from engagementwith the burner.

Another object of this invention is the production of a safety lampchimney and holder wherein the holder comprises a plurality of armscarried upon the burner so as to normally extend in vertical positions,these arms being provided with sockets in which knobs formed upon thechimney are adapted to fit so as to hold the chimney against accidentaldisplacement, these arms being mounted so as to be sprung outwardly fromengagement with the chimney and thus permit the chimney to be removed asdesired.

With these and other objects in View this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing:

Figure 1 is a side elevation of the safety lamp chimney and holder,illustrating the same in use, the chimney being broken away.

Fig. 2 is a side elevation of one of the arms, illustrating the samepartially in section, showing how the same is mounted upon the burner.

Fig. 3 is a section taken on the line 33 of Fig. 1.

- of the burner 3 Fig. 1 is a detail perspective view of a slightlymodified form of one of the arms.

Fig. 5 is a fragmentary side elevation of a portion of the chimney,showing one of the knobs mounted thereon. Referring to the accompanyingdrawings by numerals it will be seen that the chimney 1 is adapted to bemounted upon the base 2 in the usual manner. This chimney 1, however, isprovided with a plurality of lugs 4 formed thereon having flat sides5-for purposes to be hereinafter set forth.

The holder comprises a plurality of arms (3 having a bowed lower portion7 from which extends a horizontal finger 8. The base 2 of the burner 8is provided with a strap 9 struck therefrom and being offset downwardly,as shown in Fig. 2, so as to permit the finger 8 to extend therethrough.This finger 8 is provided with a lip 10 at its inner end bearing-uponthe inner side of the strap 9 thus holding the arm (3 upon the burnerwhen in use. Owing to the fact that the base 2 of the burner 3 iscomparatively flat the finger 8 fits snugly thereon and is retained inposition by means of the strap 9. It will be seen that the finger willbe held normally in a vertical plane, as shown in Figs. 1 and 2. The arm6 is provided with an outwardly punched portion 11 thereby forming aninternal socket 12, while the extreme upper end of the arm 6 is bentoutwardly as indicated at 13 to provide a directing portion fordirecting the lower end of the chimney 1 in between the arms when thedevice is in use. A depending bar 14 is formed integral upon the bowedportion of the arm 6 and extends for a considerable distance below thefinger 8 so as to support the bearing buttons 15.

When this device is in operation it will be seen that a number of thearms are carried upon the base 2 of the burner 3. As disclosed herein itis preferably desired to employ two arms so that one arm may be operatedby the thumb of one hand, while the remaining arm may be operated by thethird finger of the same hand. Therefore, the arms of the holder shouldbe carried in alinement with each other upon opposite sides of theburner, although, of course, it is necessary to employ the secondarystation ary arms 16 now in ordinary use upon burners so as to engage thechimney 1 at points intermediate the arms 6. If it is desired, however,any number of arms as shown in this invention may be employed, although,as above stated, it is only necessary to employ two. The lower end ofthe chimney l is directed bet veen the arms (3 of the holder by theupper outwardly bent ends 13. When the lower end of the chimney restsupon the base :2 it will be seen that the knobs 4i will be carried inthe sockets 12 of the arms (5. The outer sides l of the knobs arebeveled outwardly toward a point adjacent the surface of thelampvchimney 1., thereby permitting the knobs to easily ride in betweenthe arms, forcing the same outwardly as the chimney is moved downwardly.Finally these knobs will pass into the sockets 12 and will fit snuglytherein inasmuch as the shape of the lugs will conform to the shape ofthe sockets and accordingly, the sides 5 of the lugs will hold thechimney from tipping upon the burner. When it is desired to release thechimney the bearing buttons 15 may be gripped by the thumb and the thirdfinger of the operators hand and being urged toward each other the upper1 ends of the arms will be swung outwardly from engagement with thechimney, as indicated by dotted lines at one of the arms in Fig. 1, thuscausing the knobs l of the lamp chimney l to be removed and freed fromthe sockets l2 and at this time it is obvious that the chimney may beremoved. As soon as the buttons 15 are released, however, the arms willswing back to their normal vertical positions for it will. be seen thatthe same are formed upon the fingers 8 so as to cause the resiliency ofthe arms and the fingers to normally retain the arms in a verticalposition and, therefore, when suflicient pressure is brought to bearupon the arms they will be swung againstthe tension of the fingers 8. 7By referring to Fig. lit will be seen that a slightly modified form ofarms has been disclosed in which the arm as shown is formed from asingle sheet of material. This arm 16 has the bulged portion 17 fromwhich depends the bar 18. The finger 19 is struck from the bar 18 so asto extend at right angles to the finger 16 of the bar 18. This finger 19is provided with a lip 20 for holding the same upon the burner in amanner similar to which the finger 8 of the preferred form is retained.The lower end of this bar is rolled to provide the bearing sleeve 21upon which pressure is applied when it is desired to swing the arm 16from engagement with the lamp chimney 1. This arm 16 is provided with anoutwardly struck signature.

tongue 22 which is bent so as to form a receiving socket 23, while theupper end of the arm is bent outwardly as shown at 24. The operation ofthis modified form of the arm is similar in all respects to theoperation of 'the preferred form. The only difference in theconstruction resides in the fact that instead of punching the arm toprovide a socket the tongue 22 is struck outwardly and bent to form asocket, while the lower end of the arm is rolled so as to providethebearing sleeve 21. It is, of course, obvious by referring to Fig. 2 thatthe finger 8 is struck from the depending bar 14 when the arm is beingconstructed so that this arm will also be formed from a single strip ofmaterial with the exception of the bearing buttons 15.

From the foregoing description it will be i seen that a very simple andefiicient holder has been provided for a lamp chimney which is providedwith sockets in its arms so as to receive the knobs upon the sides ofthe chimney forholding the chimney in a set position upon the burner. Itwill further be seen that the arms are formed from blank sheets ofmaterialthereby causing the same to be more. positively held in a setposition without danger of injury thereto, while the fingers beingstruck from the arms will form a resilient support for normallyretaining the arms in a vertical position for retaining the chimnev whenthe same is in operation, although it will be seen that by the smallpressure applied to the arms, the arms may be swung outwardly forreleasing the chimney.
